So far the best strat that has worked for us, is having our MT grab Steelbreaker and tank him near the front door, and an OT picking up Morogrim (or whatever his name is) and tanking him to the left hand side of the room. (Left hand as you are looking at them). We don’t even worry about a tank on Brundir until after Steelbreaker is down.
Basically we pop heroism as soon as possible on Steelbreaker so we can get him down faster. We have one healer on Morogrim Tank and 1.5 on the Steelbreaker tank. We send out .5 tank healer to help on Moro just as Steelbreaker is dying – approx 10% as the tank on Moro ends up taking more. We all race over to Moro, with the Steelbreaker tank going and picking up Brunir.
Our last good attempts we got Brundir to about 50% before we just had too few alive.
The Runes of Death lived up to their name and just kept killing people.
Seems to work well for us, just hoping we can get some good practice in as I think this is a winner.
